Abstract

This study presents the tensile strength and surface roughness resulting from friction stir welding (FSW) on the lap joint method using AA 6061 –T6. FSW is conducted by comparing three different tool pin shapes: hexagon, thread, and square. Overlap welding using the FSW method is challenging if machine parameters, such as spindle speed and feed rate, are incompatible. The experiment was conducted using a conventional milling machine with a spindle speed of 1400 -1750 rpm and a feed rate of 20 – 30 mm/min. The results show that a spindle speed of 1750 rpm and a feed rate of 30 mm/min using a square tool pin results in 83.5088 MPa ultimate tensile strength and 0.85 µm surface roughness (Ra), which is much better than hexagon and thread type tool pins. In addition, the overall results on all three tool pin shapes show that higher processing parameters increase tensile strength and surface roughness. This study revealed the effect of parameters on AA6061 –T6 and the resulting implications of mechanical strength and surface roughness.

刀销轮廓对AA6061-T6重叠头搅拌摩擦焊机械强度和表面粗糙度的影响

研究了AA 6061 -T6搅拌摩擦焊搭接法的拉伸强度和表面粗糙度。FSW是通过比较三种不同的工具销形状来进行的:六边形、螺纹形和方形。如果机床参数(如主轴转速和进给速度)不兼容，则使用FSW方法进行叠焊是具有挑战性的。实验采用常规铣床进行，主轴转速为1400 ~ 1750 rpm，进给速度为20 ~ 30 mm/min。结果表明:在主轴转速为1750 rpm、进给速度为30 mm/min的条件下，采用方形刀销可获得83.5088 MPa的极限抗拉强度和0.85µm的表面粗糙度(Ra)，明显优于六角刀销和螺纹刀销;此外，所有三种刀具销形状的总体结果表明，较高的加工参数增加了抗拉强度和表面粗糙度。本研究揭示了参数对AA6061 -T6的影响及其对机械强度和表面粗糙度的影响。

期刊介绍： The Journal of Mechanical Engineering & Sciences "JMES" (ISSN (Print): 2289-4659; e-ISSN: 2231-8380) is an open access peer-review journal (Indexed by Emerging Source Citation Index (ESCI), WOS; SCOPUS Index (Elsevier); EBSCOhost; Index Copernicus; Ulrichsweb, DOAJ, Google Scholar) which publishes original and review articles that advance the understanding of both the fundamentals of engineering science and its application to the solution of challenges and problems in mechanical engineering systems, machines and components. It is particularly concerned with the demonstration of engineering science solutions to specific industrial problems. Original contributions providing insight into the use of analytical, computational modeling, structural mechanics, metal forming, behavior and application of advanced materials, impact mechanics, strain localization and other effects of nonlinearity, fluid mechanics, robotics, tribology, thermodynamics, and materials processing generally from the core of the journal contents are encouraged. Only original, innovative and novel papers will be considered for publication in the JMES. The authors are required to confirm that their paper has not been submitted to any other journal in English or any other language. The JMES welcome contributions from all who wishes to report on new developments and latest findings in mechanical engineering.
